I would take it off and have a radiator shop check it out. They should tell you if it's worth restoring, or needs replacing. Sounds like it needs more than a little back flushing would accomplish.
Hi there:the Audi manual never talks about a 2 stage aux fan just that the aux fan runs with ac on and it can run with out ac on if there is an overheat issue on the coolant side where as the a4 info clearly states a 2 stage aux fan system that would lead me to think the early 4.2 did not use a 2 stage system. Your car is not overheating and boiling over out of the coolant tank it is showing a little hotter than what would be perfect but it is still in what Audi calls acceptable range. The whole coolant system is new I would start looking at your sensor and gage systems there is a coolant sensor in the rad but that is most likely new if they replaced the rad. The gage uses a temp sensor on the engine for the gage I would replace that sensor and test the gage with a resistance input tool we have at the dealer. Could be a gouge or the wiring to it. There is a coolant fan module that could be defective if your sure there was a two speeds to the aux fan.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
i just solved this on my A6 quattro check the level in your expansion tank (left side of engine bay) if level is low then top up with long life dual anti-freeze/coolant,saves any probs if we have a harsh winter, if full pump on the radiator feed to help relieve poss blockages and make sure water is flowing through the system
You didn't say what year the car is or what other diagnostics you've done lately...My guess is the radiator core is plugged...If you want to tackle it yourself, buy a Chiltons repair manual at AutoZone or NAPA stores ($25). I suspect you'll have to order the manual. Good Luck
Could be the fuel pump. If there is pressure in the fuel tank, such as on a hot day it is just enough to get the engine to sputter a few times but not keep running. Might also be the cam position sensor (left rear side of V-6 engine ). A scan reader tool would indicate that.
